CentOS7安裝Openvswitch
安裝
1、安裝依賴包:yum -y install openssl-devel wget kernel-devel
2、安裝開發工具:yum groupinstall "Development Tools"
3、新增使用者:adduser ovswitch,切換使用者並跳轉至使用者資料夾:su - ovswitch //此步驟並不是必須,僅僅為為了有一個使用者資料夾好用來執行後面的命令,可以是用當前的非root 使用者執行下面相關的命令
4、下載原始碼:wget http://openvswitch.org/releases/openvswitch-2.5.1.tar.gz
5、解壓:tar xfz openvswitch-2.5.1.tar.gz
6、建立編譯目錄:mkdir -p ~/rpmbuild/SOURCES
7、從spec檔案中刪除openvswitch-kmod的依賴包,並建立一個新的spec檔案:
sed 's/openvswitch-kmod, //g' openvswitch-2.5.1/rhel/openvswitch.spec > openvswitch-2.5.1/rhel/openvswitch_no_kmod.spec
8、開始編譯:rpmbuild -bb --without=check ~/openvswitch-2.5.1/rhel/openvswitch_no_kmod.spec
可能出現以下錯誤:
error: File /home/ovswitch/rpmbuild/SOURCES/openvswitch-2.5.1.tar.gz: No such file or directory
解決辦法:cp openvswitch-2.5.1.tar.gz rpmbuild/SOURCES
9、退出當前使用者使用root: exit
10、安裝編譯生成的rpm檔案:
yum localinstall /home/ovswitch/rpmbuild/RPMS/x86_64/openvswitch-2.5.1-1.x86_64.rpm
11、啟動服務:systemctl start openvswitch.service
12、檢視服務狀態:systemctl -l status openvswitch.service
可能出現以下錯誤:
openvswitch.service - LSB: Open vSwitch switch

解決辦法:

mkdir /etc/openvswitch
semanage fcontext -a -t openvswitch_rw_t "/etc/openvswitch(/.*)?"
restorecon -Rv /etc/openvswitch
再次使用:
systemctl stop openvswitch.service
systemctl start openvswitch.service
再次檢視服務狀態:systemctl -l status openvswitch.service
openvswitch.service - LSB: Open vSwitch switch
